Using specific content type in Camel Rest DSL

Issue

Configured consumes in REST DSL, but camel still accepts different content-types

<!-- ============== REST DSL ============== -->
<restConfiguration bindingMode="off" component="jetty"
  enableCORS="true" host="0.0.0.0" port="9000">
  <endpointProperty key="handlers" value="logger"/>
  <dataFormatProperty key="prettyPrint" value="true"/>
</restConfiguration>
<rest path="/private-api/v1">
   <post uri="/sample1" consumes="multipart/form-data"
      produces="applicatoin/json" >
      <to uri="direct:sample1"/>
  </post>
</rest>
